Patent EP-0267394-A3 (EP)
Title: Process to draw off the gases in metal smelting
IPC: F27D7/04
Filed: 1987-09-23
Abstract: In the case of the present process, the gases to be drawn off during the smelting of readily smeltable metal, such as for example lead, are not drawn off directly from the space above the smelt but via a closure device which is located in the upper part of the smelting space above the smelt. This closure device is designed in such a way that it does not seal tightly during the smelting operation, so that there is constantly an air stream, if only slight, to the drawing-off apparatus. The closure may be designed as a door, swing door, double door or airlock. In any event, a gas duct leads from the drawing-off apparatus into the space which is arranged behind the non-tightly sealing door on the side facing away from the smelting space. The metal is preferably introduced into the smelting space likewise via the non-tightly sealing closure, which according to the invention has to be closed when the metal drops into the smelt. <IMAGE>

IPC: G01N1/00
Filed: 1987-02-24
Abstract: A disposable plastic cartridge (54) contains 
three fine lightweight wire mesh collectors 
(84-1, 84-2, 84-3), each of phosphor bronze. One 
collector has an oxidized surface for collecting drug 
particulates. The other two have surfaces electro­
plated with zinc to form a rough multi-fissured 
surface for trapping low volatility vapours. In use, 
a portion of a warm sample air stream is chilled and 
passed through the collectors in parallel for sample 
collection. Simultaneously part of the sample air 
stream by-passes the chiller (18) and is fed directly 
into a mass analyzer (50) for real time analysis. 
Next, both collection and real time analysis are 
terminated, and each collector is desorbed in sequence 
with a pulse of hot air which flows into the mass 
analyzer for sequential analysis.

Patent EP-0289120-A3 (EP)
Title: Optical sensor
IPC: G02F1/01
Filed: 1988-03-10
Abstract: An optical sensor comprises a polychromatic light source (3), a detector (4), and first and second polarisers (7) (8) disposed in the light path between the source and the detector. The polarisation axis of the first polariser (7) is substantially orthogonal to that of the second (8), and there is a modulating element (6) of birefringent material disposed therebetween. The modulating element is disposed such that a change in the parameter to be measured alters the optical path length of the polychromatic light through the modulating element, thereby changing the colour of the light incident on the detector (4). The detector comprises first and second photo-responsive elements (9) (10), the responsivity with respect to wavelength of the first element (9) being different from that of the second (10). Signals from the photo-responsive elements are fed to a microprocessor (13) which calculates the colour of the light incident on the detector as represented by two or more parameters on the Chromaticity (CIE) Diagram, and interprets this colour in terms of the parameter to be measured.

Title: Precursor of pyrolytic carbon
IPC: C10C1/00
Filed: 1989-06-05
Abstract: The pyrolitic carbon precursor based on synthetic phenol residues has a softening point of about 100 DEG C (Kraemer-Sarnow) and contains only very small quantities of toxicologically objectionable substances. It pyrolyses smoothly in the range from about 200 to 800 DEG C and thus forms 30 to 40 % by weight of pyrolitic carbon. The low phenol content is achieved by a thermal distillation treatment with addition of high-boiling aromatic oils.

Title: Platinum black air cathode, method of operating same, and layered gas diffusion electrode of improved inter-layer bonding
IPC: C25B11/03
Filed: 1989-08-31
Abstract: A platinum black air cathode has an active layer and a support layer. The active layer comprises platinum black plus hydrophobic binder, typically a fluorinated polymer. The support layer may be made up from carbon black bound with a halopolymer binding agent. Such combination can provide for economical utilization of active ingredient without sacrifice of cathode structural integrity. To assist in this structural integrity, a thin support mesh may be used, preferably with the support layer. There can also be employed between the active layer and the support layer a porous bonding layer, which can find broader utilization with layered gas diffusion electrodes in general. For highly desirable, greatly extended operation of the platinum black air cathode, the cathode can be operated intermittently, or anodically polarized or be subjected to infrequent voltage suppression, as well as being involved with any combination of the foregoing.
